Hi!
After reviewing posts on bleach concentration for roofs, it seems ~1.5% bleach delivered is good. I have a downstream injector that delivers 15/1, so using 12% bleach I would end up with 0.8% bleach delivered. Is this too dilute?
If it is, a lady from the pool supply said they had 100% bleach in powder they sell for $8 a pound. If I start with 1 pound 100% bleach, add 4 pounds(pints) water I'd get 20% bleach solution. Is this how the % is calculated?
If so, then 0.20 divided by 15 would give me 1.3%, right?
So this works out to about $25/gal of 20% bleach which is like $15/gal 12%, damn pricey.
Whadaya think?
